You can then specify the "Topic" (a string used by a broker to filter messages), "Message" (the message itself), "QoS" (indicates Quality of Service level for
the message), and "Retain" (whether to retain the message or discard it) parameters.
:
note "Broker" and "Topic" field configuration is required. "Message", "QoS", and "Retain" can be optional or required - depends on how the server/broker is
set up.
MQTT with script scenario
MQTT broker can be configured with

Create a new script, use the template as a reference, change the parameters accordingly and run the script.
Every line that begins with a symbol " " is instructional and it describes the parameter that is going to be configured below the line. Change the parameters

within quotation marks "" that would apply to your specific case.
Script example:
